The stator yoke 21 of shape, simplifies the processing technology of stator yoke 21 so that stator yoke 21 can be with rapid shaping, and it is fixed to improve
The production efficiency in sub- yoke portion 21, and the material of stator yoke 21 is saved, reduce material cost.
Some embodiments of the invention, one end of the adjacent rotor 1 of at least one stator tooth 22 is (for example, in Fig. 1
It is inner) at least one tooth boot portion 222 is provided with, tooth boot portion 222 is axially extending along rotor 1.Here, it is necessary to explanation, this Shen
Please in described " interior " refer to the neighbouring center position of motor 100, correspondingly, described " outward " is referred to away from electricity in the application
The direction at the center of machine 100.
That is, one of stator tooth 22 that can be in multiple stator tooths 22 above-mentioned one end set one or
Two tooth boot portions 222, it is also possible to which above-mentioned one end of the partial stator tooth 22 in multiple stator tooths 22 sets one or two
Tooth boot portion 222, can also be respectively provided with one or two tooth boot portions 222 in above-mentioned one end of each stator tooth 22.Specifically, when
When above-mentioned one end of stator tooth 22 is provided with a tooth boot portion 222, tooth boot portion 222 can be towards the front side of stator tooth 22 or rear side
Extend, when above-mentioned one end of stator tooth 22 is provided with two tooth boot portions 222, two tooth boot portions 222 can be respectively facing stator tooth
22 front side and rear side extend.Thus, it is possible to effectively improve the utilization rate of the axial magnetic field of rotor 1, improve stator and turn
Magnetic conduction effect between son 1, so as to improve the performance of motor 100.
For example, referring to Fig. 1, Fig. 2, Fig. 8 and Fig. 9, above-mentioned one end of each stator tooth 22 is respectively provided with two tooth boot portions 222,
Two tooth boot portions 222 are respectively facing the front side of stator tooth 22 and rear side extends.Thus, the axial magnetic field of rotor 1 is effectively improved
Utilization rate.And for example, reference picture 10, above-mentioned one end of stator tooth 22 is provided with the tooth boots that a front side towards stator tooth 22 extends
Portion 222.Thus, the utilization rate of the axial magnetic field of rotor 1 can equally be improved.
Some embodiments of the invention, one end away from stator tooth 22 of at least one tooth boot portion 222 is provided with boss
221, boss 221 extends towards the direction of rotor 1.Specifically, when above-mentioned one end of stator tooth 22 is provided with a tooth boot portion 222
And tooth boot portion 222 towards the front side of stator tooth 22 extend when, the front end (i.e. the free end of tooth boot portion 222) of tooth boot portion 222 can be with
It is provided with boss 221.When above-mentioned one end of stator tooth 22 be provided with a tooth boot portion 222 and tooth boot portion 222 towards stator tooth 22 after
When side extends, the rear end of tooth boot portion 222 can be provided with boss 221.When above-mentioned one end of stator tooth 22 is provided with two tooth boot portions
222, when two tooth boot portions 222 are respectively facing front side and the rear side extension of stator tooth 22, can be before the tooth boot portion 222 of front side
End sets boss 221, it is also possible to set boss 221 in the rear end of the tooth boot portion 222 of rear side, can also simultaneously in the tooth boots of front side
The rear end of the front end in portion 222 and the tooth boot portion 222 of rear side sets boss 221.
Specifically, reference picture 8 and Fig. 9, one end of boss 221 are connected with tooth boot portion 222, the other end direction of boss 221
The direction of rotor 1 extends, that is to say, that boss 221 can radially extending along stator yoke 21.Thus, it is possible to not increase
On the basis of teeth portion punching quantity, by setting boss 221 in tooth boot portion 222 so that the distance between stator and rotor 1 are more
Adjunction is near, reduces magnetic resistance, improves the magnetic conduction effect between stator and rotor 1, and poly- magnetic effect is more preferable so that magnetic field is easier
It is directed into the stator of motor 100, improves the performance of motor 100.
Alternatively, when a boss 221 is equipped with each stator tooth 22, boss 221 is located at the thickness of stator tooth 22
The same side in direction (for example, the fore-and-aft direction in Fig. 1).For example, boss 221 can simultaneously be located at the tooth boots of the front side of stator tooth 22
The front end in portion 222, or the rear end of the tooth boot portion 222 of the rear side of stator tooth 22 is located at simultaneously.Thus, it is possible to improve motor 100
Balance quality, so as to further increasing the overall performance of motor 100.Wherein, the tooth boot portion 222 for being provided with boss 221 is prolonged
Elongation can be equal to nothing set boss 221 tooth boot portion 222 development length (as shown in Figure 8), it is also possible to more than setting
The development length (as shown in Figure 9) of the tooth boot portion 222 of boss 221.
Specifically, a side surface of the adjacent rotor of boss 221 is formed as plane, tapered plane or is directed away from rotor center
Direction protrusion cambered surface.For example, in the example of fig. 8, a side surface of the adjacent rotor of boss 221 is formed as plane, and
Such as, in the example of figure 9, the side surface formation of the adjacent rotor of boss 221 is directed away from the direction protrusion of rotor center
Cambered surface (such as arc surface).Simple structure, it is easy to process.
Alternatively, boss 221 is integrally formed with stator tooth 22.For example, boss 221 can be with punch forming, but not limited to this.
Process is simple, production efficiency is high, and processing cost is low.It is space between traditional rotor of motor 100 and stator tooth 22, magnetic conductivity is
1, and the boss 221 in the present embodiment is the extended structure of stator tooth 22, for example, boss 221 can be of silicon steel construction
Point, magnetic conductivity is significantly increased, and improves the magnetic conduction effect between stator and rotor, and poly- magnetic effect is more preferable so that magnetic field is easier
It is directed into the stator of motor 100, improves the performance of motor 100.
Specifically, the structure and size of each teeth portion punching are just the same.Thus, it is possible to improve the production effect of teeth portion punching
The utilization rate of rate and material.
Some embodiments of the invention, are formed with bayonet socket 223 on stator tooth 22, bayonet socket 223 is by the of stator tooth 22
Towards the second sidewall recessed formation relative with the first side wall, the first side wall is stator tooth 22 in the axial direction of rotor to side wall
